I went from a 4.5" roller I had been running for 15 years, it needed replacement. The one I chose to buy is the 3" version of Kompact, about a third more resistance due to the reduced roller diameter. It is indeed a significantly greater pedaling load, but the 4.5" rollers were getting too easy and I would have needed a greater load.
I work to support domestic manufacturing and smaller business. and Kreitler has been a defacto reference for rollers for decades.
No worries, fast shipping, sweet quality and great Customer Support. Very pleased.
